Thereafter, this mixture may be diluted Withwater to any desired practical extent to be used a dye or paint forappli cation to fabrics such as silk and the like.

After the coloring agent has been applied either as a stopper definingboundaries of the design, or as a dye or paint covering areas within oroutside of said boundaries, or as both, the fabric is subjected to heatfor a period of three hours or more, preferably in a chamber containingsteam and at a temperature not less than 180 degrees Fahrenheit andthenwashed in clear water and ironed. Any stiffness of portions of thefabric resulting from the application and drying of the stopper will beremoved by the subsequent heating and washing operations without,however, removing or diminishing the effectiveness of the dye colorwhich remains fast in the fabric.

Although I have mentioned the utility of the so-c'alled stopper compoundmore particularly in'connection with use of the coloring agent, paint,or dye derived therefrom as described, said stopper compound may be usedalso as a stopper where other kinds of coloring agents are used. Forexample, many known coloring agents or mediums are satisfactory from theviewpoint of color or hue characteristics and permanency. Such mediumsmay be employed for coloring areas bounded or stopped by suitableapplications of my stoppin medium, regardless of the character of thesolvent or vehicle in which the color medium is in solution orsuspension. It is preferable, however, to utilizemy. inn proved compoundwith appropriate variation both as a stopper and as a paint or dye,inasmuch as the ingredients and methods of application can bestandardized to produce equally successful results for all colors andall fabrics.

vVh1le the compound hereinabove described is referred to as a coloringagent or medium for fabrics, it is contemplated that other andappropriate and valuable uses for it will be found from time to time.

I claim as my invention:

1. A coloring agent for fabrics consisting of an acid dye stuff and aviscous substance in an aqueous solution and glacial acetic acid.

2. A coloring agent for fabrics consisting of an acid dye stuff and gumacacia in an aqueous solution and glacial acetic acid.

3. A coloring agent for fabrics consisting of Water 16 02., a dye stuifA 02., gum acacia 8 02s., and of 95% glacial acetic acid solution, 10drops.

l. The method of making a coloring agent for fabrics which includesdissolving a dye stuff in boiling water, adding thereto a fiX- iugagent, allowing themixture to cool and then adding a viscous substancesoluble in said mixture. V V

5. The method of making a coloring agent for fabrics which includesdissolving a dye stuff in boiling water, adding thereto glacial aceticacid, allowing the mixture to cool, and then adding thereto a solublegum.

6. The method of making a coloring agent for fabrics which includesdissolving A, oz. of dye stufi in 16% eras. of boiling water, addingthereto a fixing agent, allowing the mixture tocool, and then addingthereto 8% ozs. of gum acacia.

In testimony whereof, I have signed my name to this specification this13th day of May, 1927.
